i need to display high resolution scanned tiff images in oracle forms 10g. i have used read_image_file to do this. i could able to get normal tiff images but could not load high resolution scanned tiff images (size is less than 1mb) in forms. Any help would be appreciated

You haven't exactly explained what the problem is nor have you provided the exact Forms version you are using, so providing specific help will be difficult. You should alway include complete product versions when posting technical questions on any forum.

As for TIF image support, although Forms hasn't offered many changes to image support in a long time, some changes have been made. However, one thing that remains the same is that Forms does not support multi-page TIF and does not support many of the compression formats. However, Forms recently added support for TIF-G4 compression. To enable it you need to add the following to default.env:

I just tested this in 10.1.2.3 generally speaking it works. The situations that do not work are related to the file compression type and EXIF data (where applicable). I tested with a 4288x2848 image that resulted in approximately a 5.5 meg file size.

o In jpg format, the image would not load when it contained EXIF data. Once the EXIF data was removed the full image was properly displayed.

1. Install the 10.1.2.3 patch set
2. Remove ":system.message_level:=25;" from your code so you can actually see the error that results.
3. Avoid using tif if possible.
4. If avoiding tif is not possible try using a different tif format

Please refer to my previous update where I explain where you can find information on which formats are supported. I included the list in my update.

If you have determined that the file is CCITT Group 4 then you will only be able to display them when you properly set MM_USE_TIF_G4=TRUE in default.env (or your custom file if you created one). That said, I still recommend applying 10.1.2.3. Also remember that images will not appear in the Builder. They will only appear at runtime.

Finally, as previously mentioned, remove this line of code so that you can see exactly why it isn't working:
<blockquote>:system.message_level:=25;</blockquote>

Hi Michael,
you seem very knowledgable on this subject so I thought I'd give this a try.
We are running forms 10.1.2.0.2
datebase server 10.2.0.4
application server 10.1.2.3

We have a customer who does TIF images....I have an oracle form that displays that image in an image item using READ_IMAGE_FILE.
They create most of their TIF images using corel draw, saving to a .cdr file, and then exporting to a TIF file. there are different sizes.
This was working fine UNTIL we installed patch 14825718 to resolve the java 7 issues.

Is there some setting that could have gotten 'reset' from installing that patch.
The wierd thing is - this patch was installed on different servers, on one it is not failing, on the other 3 it is.

It does seem to be 'size' related....if I pick something with dimensions smaller than 1500x700, they display fine...
1500x900 seems to be a 'toss up' as to whether it will display or not.
over that fails with the FRM-92102 error and you lose connection and have to close out.

These TIFS have existed for a long time in some cases, the form has worked for years.
Any idea?

Patch 14825718 assumes you first have 10.1.2.3 in place and not 10.1.2.0. Did you try to install this patch on top of 10.1.2.0? You indicated that you have Forms 10.1.2.0 and Application Server 10.1.2.3. I'm not sure how that is possible since patching Application Server to 10.1.2.3 will also patch Forms in that environment to 10.1.2.3 also. If however you do/did have Forms 10.1.2.0 and somehow managed to get the patch installed, you may have created a mess.

Also, Java 7 is not supported for use with any Forms version older than 11.1.1.6. The patch you applied is intended for Oracle EBusiness customers only. Although there likely would not be a problem using this patch outside of the EBiz environment, understand that Oracle Support (specifically the Forms team) may not assist you with such a configuration or while using Java 7 since it is not certified with this Forms version for non-Ebiz users.

If you are finding that you have more than one server with the same patches installed and the problem only reproduces when accessing specific servers, likely the client jar cache ("Temporary Internet file") needs to be cleared. This can be done from the Java Control Panel on each client machine. This is not the same as the browser cache, so don't waste time clearing the browser. Close all open browsers then open the Java Control Panel and clear the Temporary Internet Files and retest.

However, as mentioned, your current configuration technically isn't considered "certified".

Hi Michael,
Yes our application server was at 10.1.2.3 before the patch was installed. The forms version was the forms builder....but that probably doesn't enter into the equation. The forms are compiled on the app server.
We know the patch configuration with Java 7/ oracle 10g is not supported..but we do not have control of our client machines...so this was a way to make it 'work' while we get another release together and we are upgrading to Oragle 11 in the next couple of months.
But as I said, everything seemed to be working fine, until someone got to displaying a large TIF image in one of the forms. Actually, there are three forms that allow you to display the same images...it does not work in any of the three. They do pull into reports fine and display and print.
Are there other environment variables that deal specifically with TIF files other than the one you mentioned above? which I am trying to try but my app server doesn't seem to want to come back up. ugh.

I would recommend the following (assuming you have an account with Oracle Support):

1. Create a Service Request with Oracle Support
2. Create a very simple test case which illustrates how your application loads the image into the form. Verify that you can reproduce the failure with this test case.
3. Provide Support with the test case and at least one image that works correctly and one that does not.

They should be able to help identify if the issue is in a lack of support for the image format or if there is a defect in Forms or if there is an issue in the code you are using. However, keep in mind that because Forms 10 is no longer entitled to Error Correction Support, they will run your test case against a currently supported version like 11.1.2.1. If the problem reproduces in that version and the images are deemed of a supportable format, a product defect (bug) can be filed against the new Forms version. A fix will not be provide versions older than 11.1.1.6

If you are not willing or able to contact Support, your only other option that I can think of would be to change the file format or create a java bean that supports the format you need.
